Essential Question: How do i know what number is half way between two different degrees?
Problem 1.3- Measuring Temperature
A. Arrange the following temperatures in order from lowest to highest: -8 ° ,-4 ° ,12 ° ,-2 ° , 0 ° ,-15 ° ?
-15 °, -8 °, -2 °, 0 °, 4 °, 12 °
B.The temperature reading on a thermometer is 5 celciusF. Tell what the new reading will be if the temperature
1.rises 10°
5° + 10° = 15°
2. falls 2°
5° - 2 ° = 3°
3. falls 10°
5° - 10° = - 5°
4. rises 7°
5° + 7° = 12°
C. The temperature reading on a thermometer is -5° F. Tell what the new reading will be if the temperature:
1. falls 3°
-5° - 3° = - 8°
2. rises 3°
-5° + 3 = -2
3. falls 10°
-5° - 10°= - 15°
4. rises 10°
-5° + 10° = 5°
D. In 1-6, give the temperature halfway between the two given temperatures.
1. 0° and 10° = 5°
2. -5° and 15° = 10°
3. 5° and -15° = 10°
4. 0° and -20° = 10
5. -8° and 8° = 0°
6. -6° and -16° = 11°
E. In 1-4, tell which temperature reading is farther from -2°.
1. -6° or 6°
2°
2. -7° or °3
-7°
3. 2° or -5°
-5°
4. 2° or - °5
2°
F. Explain how you determined your answer for part 4 of question E.
Part E, 4 was:Which is farther from -2°, choices: 2° or -5°.
i answered 2°, because -5° is only 3 away from -2°, where as 2° is 4 numbers away from -2°, which makes this one farther.
